NuFilter™ High Performance Custom RF Filters

The NuFilter™ product line includes quick-turn custom filters and complex custom filters. We design various filter topologies such as Bandpass, Highpass, Lowpass, and Notch filters.

Our QUICKFIL program provides quotations within 24 hours with a response plot and mechanical drawing. Receive your finished filter within 2 – 3 weeks after receipt of order. This program fulfills our quick-turn methodology of filters that are moderately complex in design and within the following parameters:

  • 1 to 20 GHz
  • 5% to 28% 3 dB bandwidth
  • Up to 50 W power handling

Are your specifications outside of these parameters? Not to worry, we cater to a full spectrum of RF filters.

Our CUSTOMFIL program provides the same expertise, but caters to more design-intensive, complex orders. The lead times reflect this complexity and can be longer than 3 weeks, typically less than 8 weeks.

Multifunction RF Power Amplifiers for Space Applications

NASA envisions that data throughput and size, weight, and power consumption (SWaP) requirements levied on future space exploration vehicles due to resource constraints will necessitate that a different approach is taken for communications and radar. Rather than employing individual systems for short-range communications, long-range communications, and radar, respectively, a common architecture would need to be

High Power Switched Filter Bank Options for RF Communications and Electronic Warfare (EW) Applications

A Switched Filter Bank is a device that combines switches and filters to provide user-selectable frequency channels. Switched filter banks are beneficial to Radio Frequency (RF) communication systems and are utilized in both receivers and transmitters to reduce signal interference from harmonics, spurious emissions, strong signal interferers, and to limit noise power for optimized system

MMICs vs. Discrete Circuits, What Are the Trade-Offs?

One of the major decisions that a Power Amplifier (PA) Module designer must make in the development process is the choice of architecture that they will utilize in the amplification circuit. The two most widely used options are to pursue a Monolithic Microwaves Integrated Circuit (MMIC) or to design around discrete components. Each of these

Constellation Diagrams The Fault In Our Stars

Constellation Diagrams: The Fault in Our Stars

Constellation diagrams are 2D graphical representations of digitally modulated signals.  They are used for the display and analysis of digitally modulated waveforms, and provide valuable insight into the performance of a digital communication system. Digitally modulated signals encode information within a sinusoidal carrier wave by mixing it with a discretized message signal, therefore modifying the

How Wireless RF and Microwaves Affect the World Around You

Radio wave applications have come a long way since it was first theorized by James Clark Maxwell in his 1873 work “A Treatise on Electricity and Magnetism”, where he laid out mathematical theories showing the potential applications of radio technology. Only fifteen years later, German Physicist Heinrich Hertz became the first person to produce, transmit,

Extending the Range of a Low Power UAV Radio

Low-power UAV radio systems, though designed for short distance communications, can be an inexpensive and reliable means of communications over greater distances – especially when the application is small UAS platforms. Many of these radios come with a variety of options including programmable bandwidths, RF power settings, and modulation type. Usually the bandwidth and modulation
